I need help about dockerfile
问题
我需要帮助。
我的项目是使用Golang编写的服务器。
这个服务器用于创建PDF文件（github.com/jung-kurt/gofpdf）。
我使用了韩文字体文件（https://fonts.google.com/specimen/Nanum+Gothic）。
我可以看到生成的PDF文件效果很好。
但是，在创建Docker镜像后，我看到了错误消息：
(err: stat go/src/pdf.server/templates/font/NanumGothic-Regular.ttf: no such file or directory)
为什么会这样？我在Dockerfile中进行了复制操作：
COPY /cert/Wildcard.sunmediscreen.com.key.pem /go/src/pdf.server/cert/
COPY /cert/Full_Wildcard.sunmediscreen.com.pem /go/src/pdf.server/cert/
COPY /templates/font/NanumGothic-Bold.ttf /go/src/pdf.server/templates/font/
COPY /templates/font/NanumGothic-ExtraBold.ttf /go/src/pdf.server/templates/font/
COPY /templates/font/NanumGothic-Regular.ttf /go/src/pdf.server/templates/font/
这是Dockerfile的日志：

---> e9d027f3cefb
Step 25/28 : COPY /templates/font/NanumGothic-Regular.ttf /go/src/pdf.server/templates/font/
---> 2a9c96090552
这是Golang的代码：
fontDir := filepath.Join(os.Getenv("GOPATH"), "src/pdf.server/templates/font")
pdf.AddUTF8Font("NanumGothic", "", filepath.Join(fontDir, "NanumGothic-Regular.ttf"))
pdf.AddUTF8Font("NanumGothic", "B", filepath.Join(fontDir, "NanumGothic-Bold.ttf"))
pdf.AddUTF8Font("NanumGothic", "EB", filepath.Join(fontDir, "NanumGothic-ExtraBold.ttf"))
只有字体文件存在问题。
请帮助我解决这个问题。
os.Getenv("GOPATH")
这个路径没有问题，
因为.pem文件的路径在TLS设置方面没有问题。
crtpath := filepath.Join(os.Getenv("GOPATH"), "src/pdf.server/cert/Full_Wildcard.sunmediscreen.com.pem")
keypath := filepath.Join(os.Getenv("GOPATH"), "src/pdf.server/cert/Wildcard.sunmediscreen.com.key.pem")
var x509 tls.Certificate
x509, err := tls.LoadX509KeyPair(crtpath, keypath)
if err != nil {
panic(err)
}

pdf.AddUTF8Font("NanumGothic", "EB", filepath.Join(fontDir, "NanumGothic-ExtraBold.ttf"))
just font file has a problem
please help me
os.Getenv("GOPATH")
this path are no problem
because pem file path has not problem about tls setting
crtpath := filepath.Join(os.Getenv("GOPATH"), "src/pdf.server/cert/Full_Wildcard.sunmediscreen.com.pem")
keypath := filepath.Join(os.Getenv("GOPATH"), "src/pdf.server/cert/Wildcard.sunmediscreen.com.key.pem")
var x509 tls.Certificate
x509, err := tls.LoadX509KeyPair(crtpath, keypath)
if err != nil {
panic(err)
}

在err: stat go/src/pdf.server/templates/font/NanumGothic-Regular.ttf: no such file or directory中，路径缺少了根目录/，应该是/go/src/pdf.server/templates/font/NanumGothic-Regular.ttf。
fmt.Println(os.Stat("go/src/pdf.server/templates/font/NanumGothic-Regular.ttf"))
fmt.Println(os.Stat("/go/src/pdf.server/templates/font/NanumGothic-Regular.ttf"))
输出：
<nil> stat go/src/pdf.server/templates/font/NanumGothic-Regular.ttf: no such file or directory
<nil> stat /go/src/pdf.server/templates/font/NanumGothic-Regular.ttf: no such file or directory
英文:
path in err: stat go/src/pdf.server/templates/font/NanumGothic-Regular.ttf: no such file or directory missed the root directory /, it should be /go/src/pdf.server/templates/font/NanumGothic-Regular.ttf.
fmt.Println(os.Stat("go/src/pdf.server/templates/font/NanumGothic-Regular.ttf"))
fmt.Println(os.Stat("/go/src/pdf.server/templates/font/NanumGothic-Regular.ttf"))
output:
<nil> stat go/src/pdf.server/templates/font/NanumGothic-Regular.ttf: no such file or directory
<nil> stat /go/src/pdf.server/templates/font/NanumGothic-Regular.ttf: no such file or directory
